The trailer teases the fates of both Lydia and Sheriff Stilinski, and it also shows Malia (Shelley Hennig) telling Scott as they face a monster, "We're going to die down here." Scott then replies that she's wrong: "Because you're not the only one I called." At that, familiar face Chris Argent (J.R. Bourne) returns to the fray — and he's packing some serious heat.
